Step-sister's forbidden play with mother's toys uncovered by step-brother

I stumbled upon my step-sisters indulging in some naughty play with my mom's toys. They thought they had kept their little secret hidden, but I couldn't help but peek in on their forbidden fun. My step-sister and my girlfriend, both with big asses and big tits, were getting down and dirty with each other. I couldn't resist the urge to join in, and I found myself fucking my step-sister while my girlfriend looked on. It was a wild and intense moment, one that I won't soon forget. But as soon as we finished, my step-sister was quick to cover up our tracks, leaving no evidence of our forbidden play. It was a thrilling experience, one that left me craving more.
